Elevator overrun systems

An elevator system comprising:

• a first body arranged to be fixedly mounted to a portion of an elevator shaft of the elevator system;
• a second body movably arranged within the first body and slidable from a deployed state to a retracted state to within the first body;
• and
• a limit switch located at a distal end of the second body, the limit switch configured to interact with a car switch arranged on an exterior of an elevator car to prevent movement of the elevator car, wherein the car switch is at least one of mechanical and electrical;
• and
• a second body contact located at an end of the second body opposite the distal end,
• wherein the first body includes a lower contact at a first location and an upper contact at a second location,
• wherein the second body contact is slidable along the first body between contact with the lower contact of the first body in the deployed state and contact with the upper contact of the first body in the retracted state, and
• wherein the physical position of the limit switch is adjusted within the elevator shaft when transitioning between the deployed state and the retracted state.

A method of operating an elevator system having an elevator overrun system including a first body arranged to be fixedly mounted to a portion of an elevator shaft, a second body movably arranged within the first body and slidable from a deployed state to a retracted state within the first body, a limit switch located at a distal end of the second body, the limit switch configured to interact with a car switch arranged on an exterior of an elevator car to prevent movement of the elevator car, wherein the car switch is at least one of mechanical and electrical, and a second body contact located at an end of the second body opposite the distal end, wherein the first body includes a lower contact at a first location and an upper contact at a second location, wherein the second body contact is movable along the first body between contact with the lower contact of the first body in the deployed state and contact with the upper contact of the first body in the retracted state, and wherein the physical position of the limit switch is adjusted within the elevator shaft when transitioning between the deployed state and the retracted state, the method comprising:

• moving the elevator car within the elevator shaft to a first level;
• operating the elevator overrun system from the deployed state to the retracted state;
• and
• moving the elevator car to a third level that is higher in the elevator shaft than the first level.
